V to provide an intervening hollow baffle between the combustion chamberand ues for obtaining the most intensive action of the heat.

This object and other ancillary advantages are attained by theconstruction and arrangement of the heater'walls and water sectionsillustrated in the accompanying drawings forming parthereof, in which-Figure 1 isa front elevation of the heater showing the right side brokenyaway and the sections therein rotated upward upon the axis of the lowerconnecting nipples, to show an under side view of the rotated sections.

Fig. 5, a section on line 5-5, Fig. 2, of one of the intermediate watersections; and

Fig. 6, a section as on line 3 3, Fig. 2, of a modified i'orm of anintermediate water section.

Similar numerals refer to similar parts throughout the drawings.

The heater is made oi' a number of hollow water sections 1, 1a and 1b,connected together at their upper ends by the series of nipplesy 2, andat their lower ends by the series of nipples 3, by means of which theinterior of one water section communicates above and below, withtheinterior of another section; so that the water or steam can circulatefreely in and among the sev-y eral sections.

1 The forward portion of thelower ends of the intermediate watersections 1a and 1b are shaped to form the combustion chamber 4, belowwhich may be provided grate bars 5 for carrying the coal 6 or other formof fuel. For this purpose the forward portions of the lower ends of theintermediate water sections extend first horizontally rearward, as at 7,above the combustion chamber 4, thence diagonally vdownward andrearward, as at 7, at the back of the upper portion of the combustionchamber, thence rearward with a slight downward inclination, as at 7b,to a point above the rear end of the grate, bars, and thence directlydownward to the lower end of the section.

The outer side lportion S of each end section is extended downward tothe base panels to form the sides of the combustion chamber 4, and afront plate, which may be in the form of a hollow water wall 9isprovided for closing the front of the combustion chamber, which isthusformed between the outer walls of the side sections and the forwardportions of the lower ends of the f intermediate sections as describedabove.

Certain portions ot' at least one side wall of each water section arerecessed ory offset inward to form. the combustion iiues l0, the mixingflues 11, the forward smoke flue 12, the rearward smoke flue 13, theoutlet smoke yflue 1% leading to the smoke manifold 15, and the handholds 16, when the water-sections are assembled side by side.

The recesses forming these tlues, excepting the smoke outlet Hue 14,-are located at a substantial distance below the upper ends 17 of thesections, thus forming the water or steamchambers 18 of substantiallength, depth and width, in the upper end of each section, correspondingto the steam dome of an ordinary steam boiler.

Extending' first diagonally downward from the middle portion of thewater chamber 18, andthence directly rearward at an interval above thelower yend of each section, is provided the hollow flue baiiie 19 and19a, which divides the combustion and mixing iues from the smokeY lues.The hollow of this baliie communicates'with and forms part of the waterchamber in each section, and it is evident that the walls of the bailleare subject throughout their extent to the action of thel heat in theseseveral iiues.

Along the intermediate diagonal portion 7a of the lower end of eachwater section, is provided the laterally extendinghollow bailie'20,which baffle is entirely surrounded above, in rear and below .by thecombustion and mixing iues and in front by the combustion chamber andthus may be said to intervene between sailliues and chainber. The hollowof this baille communicates with and forms part of the water chamber ineach section, and its end and side wal-ls are therefore subject to thedirect, and thus the inost intense action of the heat in the combustionchamber and combustion flues.

In the middle of the rear end part of each sect-ion, is provided thehorizontal hollow baille 2l, which forms the division between l theforward and rearward sinolre flues, and may also divide the upper andlower hand holds lo, as shown in Fig. 2, which hand holds are normallyclosed by the door 22. And liiially, the inlet pipe leads into the lowereiid of one water section and the outet pipe 2l leads out of the upperend of one of the water sections, for circulating water oi steam throughthe heater.

By reason of the peculiar formation of the dues in the sides ofthesections by recessing or offsetting the saine inwardly, it will beevident that each of the battles is in direct lateral communication withthe adjacent water chamber proper, so that when the water in the baliiesbecomes highly heated or steam is produced, on account of thesubjectioii of the battles to the more intense heat from Vthe combustionchamber', such steam or water is permitted to rise immediately to theupper portion of the chamber and thus give way to the cooler watersentering from the chamber proper.

-lt will be understood that the slight intervals between the adjacentrimrportions and the edges of the baffles of each water section, areclosed by a fire cement in the usual manner employed in `heaters of thistype, thus closing these intervals and completing the formation ofthecombustion chamber and the several lines as herein described.

ln the use `of the heater with coal, colte or other lilre fuel 6, itisevident that the saine will naturally lill the combustion chamber uptothe lower end of the intervening battle 20, thus forming a partialclosure of the lower sides of the mixing flues ll; and that thepartially consumed fuel will accumulate below and to the rear of theintervening baille, while the freshly fed fuel will be located in frontthereof.

The more active 'flames of iire and gases of combustion will risedirectly'upwardand rearward against the intervening baille 20, andaround the upper ends thereof into the vupper ends of the combustiontlues and against the lower walls 23 ofthe water chambers l0, thencethese flames and gases pass rearward and downward through the combustion'flues between the forward wall of the iue baffle 19 and rearward wallof the intervening` baffle 20, at the lower end whereof they join andmix with the additional air and gases which find their waynee/acaethrough the partly consumed fuel located on the rear end of thegrate bars; whence the combined gases will be carried directly rearwardthrough the mixing tine ll and thence irst forward and then rearwardthrough the sinolre flues l2 and 13, and thence upward through theoutlet iiue ll, so that a substantially complete combustion can beaccomplished before the gases finally leave the heater through the moltemanifold lo, thereby utiliziiig substantially all of the heat unitsarising from the complete combustion of the fuelgases.

t is evident that the peculiar location of the intervening baille ofeach water section and its arrangement with reference to the chamber andiiues which entirely surround it, subjects this baille and the watercontained in the hollow thereof, to the most intense, action of the heatarising `from the 8 burning of the fuel and the initial combustion ofthe gases thereof; and that the location and arrangement of the mixingand smoke ues issuch that all the heat unitsA arising from the completecombustion of the fuel gases will be brought into play against thevarious walls of thefwater sections for heating the water contained inthe hollow battles and chambers thereof.

lu the modified form of one of the interc mediate water sections shownin Fig. 6, the side walls thereof are offset or recessed on both sidesto form the several flues, which is an obvious modification which doesnot depart from the general idea or spirit of the le@ invention.
